It’s a keeper for sure. It’s got a fantastic gun; very accurate, great handling, and the highest (unless things changed) DPM of any tier X heavy. It’s even capable of perma-tracking enemies who don’t have a good repair skill.

While it has a turret that’s mounted at the rear, You don’t really want to sidescrape all that much in the 215b, your best bet is to go hulldown- use that good gun depression and strong turret front. You’re better off playing this as a support gunner until you get into a nice position where you can cover the hull up, then you can go toe-to-toe with just about anything.

It has a very long learning curve, probably the longest at tier X. That rear mounted turret can be very awkward to get used to. The armor profile is also very hard to master. The gun and turret are amazing so you just have to practice in it.

I would never sell a tier 10, period. The game is constantly being rebalanced and if a tank isn’t being played much, or is underperforming, it could get a buff in the future. There was a time that the e3 was probably the worst tier 10, now it’s one of the strongest.
